Structure of the TFIIIC subcomplex τA provides insights into RNA polymerase III pre-initiation complex formation

Transcription factor TFIIIC plays roles in Pol III transcription and in chromatin organization. CryoEM structure of the yeast TFIIIC subcomplex τA, a negative stain reconstruction of τA bound to the TFIIIB subunits Brf1 and TBP and accompanying biochemistry suggest how τA achieves positioning of TFI...

Sumario:Transcription factor TFIIIC plays roles in Pol III transcription and in chromatin organization. CryoEM structure of the yeast TFIIIC subcomplex τA, a negative stain reconstruction of τA bound to the TFIIIB subunits Brf1 and TBP and accompanying biochemistry suggest how τA achieves positioning of TFIIIB upstream of the TSS and remodeling of the TFIIIC complex during assembly of TFIIIB.
